Description
Technical field
The present invention relates to a kind of tow, relate in particular to a kind of cigarette-filter tow and preparation method thereof.
Background technology
Cigarette filter is the important component part of cigarette, can improve the cigarette mouthfeel and reduce the injury of harmful substances from flue gases to human body.The material for preparing in the market cigarette filter mainly contains acetate fiber and polypropylene fibre, the cigarette filter combination property that acetate fiber is produced is superior, be mainly used in medium-to-high grade cigarette, but it to take the timber of high-quality be raw material, production process is complicated and be accompanied by many pollution problems.China's Forest Resources is limited, acetate fiber can not be self-supporting, need a large amount of imports every year, but the enhancing day by day along with day by day serious and people's environmental consciousness of deforestation, a lot of countries have limited deforestation, cause being becoming tight supply day of the interior acetate fiber of global range, hold at high price, this has determined that cellulose acetate fibre can not be used in a large number in low and middle-grade cigarette, acetate fiber itself can be degraded in addition, but after esterification, biodegradability descends to some extent, generally need 15 years ability biodegradable fully, it is no longer proper degradable material, the polypropylene fibre source is abundant, and production process is simple, and price is lower, and still, due to the design feature of itself, the poor-performings such as filter tip outward appearance, hardness, obstruct and the absorption of its production, can only be for low and middle-grade cigarette.
In recent years, the biodegradated polymer materals such as PLA, polyhydroxyalkanoate and poly butylene succinate had had development, particularly PLA fast, biodegradation, in natural conditions or under people's concrete conditions in the establishment of a specific crime, can occur in PLA, finally generates carbon dioxide and water, does not stay any pollutant, is genuine green material, the PLA source is abundant, its raw material sources are in native starches such as corn, Ipomoea batatas, its resource can be regenerated, and PLA has good processing characteristics, can adopt the various processing methods of general thermoplastic to be processed, comprise melt spinning, PLA has filtration to some harmful substance in flue gas in addition, possesses the good condition with filter filament as the Novel tobacco that replaces acetate fiber and polypropylene fibre, but there is following problem in filter filament prepared by unmodified poly-lactic acid material: the heatproof typing is limited in one's ability, after the filter tip of preparation is arranged on cigarette, when cigarette is pumped to while approaching filter tip, filter tip can be due to flue-gas temperature too high and moment drop-head, fume leakage, reduce filter-tip adsorptivity, current cigarette-filter tow is general in addition adopts traditional process to prepare, have following problem: first filter filament moisture pick-up properties is general, the rate of getting damp is 0.4%～0.6%, have a strong impact on filter-tip adsorptivity and compatibility, cause the alkoxy free group contained in flue gas, alkyl diradical, carbon monoxide, tar and content of beary metal can't meet the New Set of " Framework Convention on Tobacco Control ", after current tow preparing makes filter tip and is arranged on cigarette, general tar content is 15mg, nicotine content is 1.5mg, alkoxy free group and alkyl diradical Content are 14mg, carbon monoxide content is 14mg, it is two in preparing the process of filter filament, when curling in crimping machine, due to the crimping wheel high speed rotating, friction place of tow and curling wheel face, doctor blade actinal surface can produce high heat, and cause tow to produce stiffization of nodositas, at the filter tip hardness prepared after filter-stick forming device shredding gluing >=90%, Zhou Yuandu >=0.3mm, become defective work.
Summary of the invention
It is raw material that a technical problem to be solved by this invention is to provide a kind of poly-lactic acid material of take blending and modifying, can improve the tow heat distortion temperature, can not cause at cigarette smoking near the standby filter tip of this tow preparing the time, filter tip can be because flue-gas temperature be too high the cigarette-filter tow of generation moment drop-head;
Another technical problem that the present invention will solve is to provide a kind of by improvement tow moisture pick-up properties with improve tow get damp rate, adsorptivity and compatibility, reduce the harmful substances such as tar, carbon monoxide, alkyl diradical, alkoxy free group and heavy metal element that contain in flue gas, meet the New Set of " Framework Convention on Tobacco Control ", can avoid in addition producing the cigarette-filter tow preparation method of stiffization of nodositas in curly course.
